O. Nachtmann, C. Schwanenberger
TL;DR
This paper investigates the potential for detecting CP-violating effects in Z boson decays to four jets, focusing on a hypothetical triple gluon coupling and proposing observable strategies for experimental searches.
Contribution
It introduces a novel analysis of CP-violating triple gluon interactions in Z decays and suggests experimental methods to detect such effects using LEP 1 data.
Findings
CP-violating effects could influence Z -> 4 jets decay width
Proposes CP-odd observables for direct search strategies
LEP 1 data can provide significant constraints
Abstract
We analyse CP-violating effects in Z -> 4 jet decays, assuming the presence of a CP-violating effective triple gluon coupling. We discuss the influence of this coupling on the decay width. Furthermore, we analyse different CP-odd observables and propose strategies of a direct search for such a CP-violating GGG coupling. The present data of LEP 1 should give significant information on the coupling.
